Trivia: Chickens don't have teeth, even though every chicken in this film is shown to have a full set. This is because of the traditional Aardman animation to have every single character to have a cheesy grin.
Trivia: During the credits the two rats' argument about "the chicken or the egg" continues. There's also a short clip of Rocky telling them to shut up.
Trivia: There was a major push to get the film nominated for Best Picture at the Academy Awards. The failure to get the nomination, and the popularity of the film among Academy members led to the inclusion of Best Animated Feature for the next Academy Awards (2002), which was won by fellow Dreamworks film Shrek.
